+%D Since I only had the draft of MathML 2 and later 3 as example of
+%D rendering, there are probably a lot of omissions and
+%D misinterpretations. At least I learned some bits and
+%D pieces of math rendering.
+%D
+%D The main complications were not so much the math, but to
+%D find the most efficient way to handle elements without
+%D spacing beging messed up. The first implementation was
+%D aimed at getting reasonable output, this second
+%D implementation is already better in terms of handling
+%D nesting, and I will definitely need a third one that has
+%D more efficient and less ugly code.
+%D
+%D The \TEX\ part is not that complicated and once the
+%D preprocessor was okay, the rest way just a lot of keying
+%D and testing. It all comes down to gobbling, redefining,
+%D and not so much to parsing.
+%D
+%D The second implementation expanded the whole math sequence
+%D into an internal \TEX\ representation. This is a rather clean
+%D and fast process. Filtering and testing takes place by
+%D redefining teh internal representation macros.
+%D
+%D The third implementation may look a bit more messy in some
+%D respects. This is because in \TEX\ it's not that trivial to
+%D implement a tree handler. We use a stack for the \type {apply}
+%D element and other sequential content. Occasionally we need to
+%D peek into child elements which involves messy code. This
+%D implementation is closer to the normal \XML\ handling in
+%D \CONTEXT.
+
+%D We start with the parent elements and the option handler.

+%D We use inner and grouping (begin/end and no b/e) else we
+%D get problems with 1/2(1+2) and alike (todo: ask taco).
+%D
+%D The problem with apply is that we need to take care of
+%D several situations, like:
+%D
+%D \starttyping
+%D <apply> <.../> ...
+%D <apply> <fn> ...
+%D <apply> <apply> <ci> ...

+%D Because we translated version 2 of this renderer into

+%D more complex than actually needed.
